Optimus Yellow Sound Level Meters

The Optimus Yellow sound level meters are for noise measurement applications that demand an accurate and repeatable Type 1 or Type 2 device, but do not need parameters such as Leq or Lavg that you get from an integrating meter.

OSHA Occupational Noise - These meters make all the noise measurements required to satisfy the OSHA occupational noise regulations. For rapidly varying noise levels, we recommend an Integrating meter, but for a basic survey these meters are ideal.
